FM Transmitter and FM Radio Transmitters, 3 Volt FM Transmitter
The most powerful FM Transmitter circuit we've seen that operates on such low voltage (just two AA cells). A range of 200 ft can be expected and, given a good antenna and FM receiver, over 1/4 mile can be expected. An external power supply can be used up to 9 volts. Transmits to the FM radio band, which means you can use any FM radio to receive the transmitter. Teaches basics of FM transmitters. Microphone is included.
- L: 1-3/4" W: 3/4" H: 1/2"
- Requires 2 AA batteries (holder included, not shown in pic.) 9 volt battery can be used to increase range.
- FM Transmitter frequency is user selectable.
- Transmitter can be listened to on any FM radio.
--> This kit has not worked for me even though the instructions were simple and I had great hopes. I sent the kitI assembled to the manufacturer (Hong Kong) to figure out the problem. He could not, so he sent me another one that he assembled, but that one either did not work. If you want to try, it may be at your own risk.
--> Dont know the problem youve got, but I made up my own board and it works a treat, use earphones on receiver
